No Finnish Harpoon/ESSM-order (at least for now)

As the headline says, yesterday’s big news from the naval sector is not that Finland has ordered the Harpoon and/or the Evolved Sea Sparrow Missile (ESSM). In fact, what has happened is that the US offers for two major Finnish naval programs have become open knowledge. This happened as the US Defense Security Cooperation Agency has requested clearance for the sale of 112 RGM-84Q-4 Harpoon Block II+ ER anti-ship missiles (of which twelve are of the older RGM-84L-4 Harpoon Block II version which will be upgraded) and 68 ESSM missiles. These kinds of pre-clearances are not uncommon, and allow for a rapid deal following a (potential) procurement decision by a foreign customer (thanks to Aaron Mehta for providing insights about US export).

The background is two ongoing Finnish projects: the Pohjanmaa-class multirole corvettes and the PTO 2020 heavy surface-to-surface missile. The PTO 2020 will be found aboard the Pohjanmaa-class as well as replacing the current MTO 85M (roughly a RBS 15 Mk II) on the Hamina-class as part of their MLU as well as in truck-mounted batteries. As the MLU for the Hamina is very much underway already, the winner of the PTO 2020 will be announced during the first half of this year. I am still standing by my opinion that the RBS 15 Mk 3+ and the NSM are the two frontrunners, and would be somewhat surprised if Harpoon won the trophy (and even more so if the Exocet MM40 Block 3 did, though everything is possible).

The Pohjanmaa-class is still in the design stage, with the main contract(s) to be signed this year, and the building phase to start next year. The armament shown on renders include two quadruple mounts of PTO 2020 amidships, the new lightweight torpedo from Saab, the BAE/Bofors 57 mm Mk II deck-gun, and a battery of vertical launch system-cells (VLS). The two main VLS-systems on the market are the French Sylver and the US Mk 41 (a modernized version called Mk 57 is also available, and mounted on the Zumwalt-class). Both are available in different lengths, with the shortest Sylver, the A43 (an earlier A35 concept seems to have been dropped), being around 4.3 m long (or rather, high), and the shortest Mk 41 being 5.2 m long. The 8-cell module of the Sylver is also smaller and lighter than the corresponding 8-cell Mk 41 module, in part because the silos themselves are a few centimeters smaller. For a full run-through of the differences, see this post by the UK Armed Forces Commentary-blog, where the differences are discussed with a keen eye to the pros and cons for the British Type 26 Frigate.

Now, while some vessels, such as the current Finnish Hamina-class and the upcoming British Type 26, feature dedicated cells to their main air-defence assets, the VLS on the Pohjanmaa will likely be home to the ships main air defence weapons. This becomes evident as the ESSM offer is for the weapon quad-packed in Mk 25 modules, designed to fit the Mk 41-system. If the ESSM would be chosen, the Pohjanmaa-class would be by far the smallest vessel to feature the system. The decision to offer the Mk 41 is interesting, as there is a dedicated Mk 56 ESSM VLS-system if the sole use would be for the ESSM.

The ESSM is certainly a competent weapon, and shows what the Navy is aiming for. 8-16 cells with quad packs would provide for 32-64 medium-ranged missiles, a huge boost compared to the current 8 short-range Umkhontos found on the Hamina. While the Mk 41 is too big for the Hamina, the Mk 56 mean that half a dozen ESSM’s could potentially be fitted as part of the MLU if the Navy choose to go down that (unlikely) route. More interesting is that the ESSM could be fired from the Army’s NASAMS surface-to-air batteries, letting the Navy and Army use the same missile stock. The upcoming ESSM Block 2 will feature an active seeker based on that of the AMRAAM, and is potentially the version offered to the Pohjanmaa.

Interestingly, the AMRAAM-ER is a AMRAAM married to the engine of the ESSM, and no, I don’t know what exactly is the difference between an AMRAAM seeker married to an ESSM engine and an ESSM engine married to an AMRAAM seeker.

I am still inclined to believe that the Sylver might be the Navy’s preferred VLS due to the smaller footprint. However, as with the PTO 2020, we will just have to wait and see.

Beyond NASAMS

In the shadow of the HX-fighter competition, the state of the ground based air defences in Finland has again appeared in the headlines. The short story is that in the mid-90’s Finland acquired the Russian Buk-M1 air defence system as part of Russia paying off the Soviet balance of the clearing accounts. However, while the system certainly is competent, questions soon arose if it was wise to operate a high-tech system which the main adversary had built? Especially as knowing the exact capabilities of the radar and missile is of crucial importance when it comes to defeating radar-guided missiles.

By the mid-00’s training new conscripts on the Buk stopped, and the system was phased out (never trust a Finn who says something is retired, the last conscripts who trained on the system most likely had another ten years in the reserve, during which they were assigned to a wartime unit operating the missiles, giving a ‘real’ retirement date around 2015) and replaced by the NASAMS II.

The NASAMS is a controversial system in Finnish service. Not because it is bad, it is very much amongst the most modern ones available, but because it is of significantly shorter range than the Buk it replaced. Most crucially it has a ceiling of around 10,000 meters, meaning that most modern fighter aircraft can simply operate above this. This isn’t necessarily as big a drawback as it is often portrayed to be. Operating above 10,000 meters place high demands on sensors and weapons if you are to hit anything, and it means that you are easily spotted by air surveillance radars, meaning that the advantage of surprise is long gone by the time the target is overflown.

Still, this has left Finland without a long-range surface-to-air missile for the first time since the late 70’s, and talk about the need for something heavier has been going since the decision to procure NASAMS instead of Aster. The big question is what?

One issue which has been raised is the defence against ballistic missiles, i.e. missiles which are fired at a high angle, fly up to significant heights, and then ‘fall’ down at extreme speeds to hit a target. The Russian 9K270 Iskander-M is the embodiment of this threat, and comes equipped with either a conventional warhead (usually quoted at around 500 kg, but possibly with an option for a heavy penetrating warhead above 1,000 kg) or a nuclear one. The big improvement of the Iskander compared to the 9K79 Tochka U it replaced is the significant improvement of accuracy, which for the Iskander is quoted at a circular error probability of below 10 meters (i.e. half of the Iskanders will land within 10 meters of the intended target), meaning that it can reliably be assumed to hit individual buildings or bridges. As such, many has voiced the opinion that Finland need a system capable of shooting down ballistic missiles.

…and it is in the crossroad of these ideas that we find some of the most common misconceptions, which warrant a slight detour before looking at the latest developments.

To begin with, the ballistic missile threat is not new to Finland, nor is the associated A2/AD-problem, but these have been a part of the Soviet/Russian arsenal for decades. Even with the improved accuracy of the Iskander, it is not a war-winning weapon, as the limited number of missiles available and the rather limited damage caused by a single hit makes it impossible to take out dispersed targets. In other words, while it is possible to hit the command centre of a unit, it is not possible to wipe out the unit itself. The Iskander also needs target information before launch, meaning that it is best used against stationary targets.

Another issue often overlooked is how hard it is to shoot down a ballistic missile. Crucially, while a modern long-range air defence system can sport ranges of over 100 km against air targets (at high altitude, at lower altitude the earth’s curvature creates shadows), the corresponding ranges when trying to intercept a ballistic missile approaching at very high speed and steep angle are significantly shorter. While the exact performance is secret, some sources state that the maximum range is a few tens of kilometers, creating a significant problem with regards to how to base air defence batteries to be able to protect a certain target. The implications of this is that a single battery might have a hard time defending both the Upinniemi naval base and central Helsinki, depending on the parameters of the intercept.

As such, it is no surprise that Finnish officers are focusing on dispersion and hardening strategic targets instead of acquiring anti-ballistic missile capabilities. This is in marked contrast to Sweden’s decision to acquire the Patriot. Here, while the decision is not yet finalised, the ability to field the PAC-3 missile (or potentially the upcoming PAAC-4/Stunner/SkyCeptor) to take down ballistic missiles has played a key role. However, the capability doesn’t come cheap, as the total price tag of approximately 1 to 1.2 billion Euro will buy three to four batteries, each with a single radar and three to four launchers. However, the amount and types of missiles acquired will also play a huge role when it comes to cost, and the preliminary request, described as being “generous in size”, lists 200 PAC-3 (for anti-ballistic missile use) and 100 PAC-2 for use against aircraft, for an additional 1.5 billion Euro. The exact kind of combat management system involved will also play a role, as it seen in the case of the 8.6 billion Euro Polish deal for a comparable number of firing units (four batteries with four launchers each, with 208 PAC-3 missiles) as the Swedish order.

All things considered, any kind of anti-ballistic missile coverage is probably outside of the scope of the Finnish Army’s wishlist, with the focus being solely on the ability to shoot down aircraft at longer and higher ranges than what the current equipment is capable of. However, even within these bounds, there are still a significant number of different options available on the market. With this in mind the Logistics Command has now issued a Request for Information to “around ten” companies. Interestingly enough, the interview with brigadier general Renko, deputy chief of the Logistics Command, says that he would like the new missile to be part of the current NASAMS systems. At the same time, he notes that this is not purely about introducing a new missile to old launchers, but that there needs to be more batteries out in the field to improve coverage.

The obvious choice which has figured in reporting is the AMRAAM-ER. Where the basic NASAMS uses the same AMRAAM missile as found on e.g. the Finnish F/A-18 Hornets, the AMRAAM-ER marries the basic AMRAAM seeker (with improved steering code) to the engine of the ESSM (Evolved Sea Sparrow surface-to-air missile), giving a significant increase in both range and ceiling (50 and 70% respectively according to Raytheon). This means that both goals of the RFI could be met by buying more NASAMS batteries, and having both baseline and ER-versions of the AMRAAM in service. The big problem for the AIM-120 AMRAAM is that it is something of a victim of its own success. It is operated by a stunning 37 countries, meaning that no small amount of Russian research is likely going into how to defeat it. Especially if the AMRAAM will continue to be a key part of the Finnish airborne air defences as well, which is likely to be the case unless Rafale takes home the HX-competition, it might be good to ask whether all air defence eggs should be placed in the same basket?

At this point it should be remembered that one of the key points of the NASAMS is its modularity. It is unclear exactly which parts are integrated into the Finnish NASAMS systems, e.g if our ITO 05 (RBS 70 BOLIDE) are able to plug into the NASAMS’s Fire Distribution Center (FDC), something which Kongsberg claim is possible. However, if the Army really likes the current AN/MPQ-64F1 Improved Sentinel radar and associated systems, another missile could potentially be integrated into it. It is hard to see the reasoning behind this, and I am tempted to believe that the journalist misunderstood the general, who instead expressed a wish for the new system to be part of the current Finnish integrated air defences, i.e. sharing the same air picture as well as command and control structures.

If we assume this is what the Logistics Command means, it opens up a vast number of possibilities. One is the very same SAMP/T-system which competed (and lost) against the NASAMS ten years ago. The SAMP/T, also known as ASTER, is the closest competitor to the Patriot, and is also available both with “normal” and anti-ballistic missile missiles. As was the case last time around, both it and Patriot will probably be judged to be too expensive (although the Swedish deal is controversial at it turned out the SAMP/T offer was 150 million Euro cheaper than the Patriot one).

However, below the high-end Patriot and SAMP/T there are still plenty to choose from. MBDA, the company behind SAMP/T, offers the CAMM-ER and ASPIDE 2000, and while information is somewhat scarce, both are likely superior when it comes to range and height compared to the baseline AMRAAM. Saab has the SRSAM BAMSE, which offer an altitude coverage of 15,000 meters, and the benefit of operating on a different wavelength, Ka-band as opposed to X-band, than the NASAMS, making it harder to jam both at the same time. Israeli company Rafael offer the SPYDER-MR featuring their Derby-missile with a range of 50 km and a ceiling of 16,000 meters. A more exotic (and highly unlikely) option is the Japanese Type 11 missile system built by Toshiba, of which very limited information is available. Still, it does look like it could potentially fit the bill, and during the last years Japan has opened up for potential arms exports. South African Denel Systems has a number of different versions of the Umkhonto, the basic IR-version of which is currently in service with the Finnish Navy. Some of the more advanced concepts might be able to compete with the baseline AMRAAM, though it is doubtful if they will have enough reach to satisfy the demands of the current RFI. Still, Denel does offer a ground-based launcher, and is probably included amongst the companies receiving the RFI.

The winner of the eventual RFQ which is to follow the current RFI is likely found amongst those mentioned above. The defence forces would like to sign a deal in 2020, and notes that this is tied to HX and Squadron 2020, as all three programs play significant roles in the overall air defence of Finland. If e.g. the CAMM in its sea-going version is adopted for SQ2020, it might increase the chances for CAMM-ER being adopted as the ground-based solution. In the meantime, it does feel like the AMRAAM-ER is the favourite, with the big question being whether relying too much on a single missile seeker for both air and ground-based is too high a risk compared to the synergies it would give?

And as it happens, Kongsberg and Patria a week ago announced that they will open a Missile Competence Centre in Tampere, specifically mentioning their work NASAMS in the press release. Funny how these things come together sometimes.

The New Bug in Town – Versions for Finland

One issue that has been open to much speculation is exactly which version(s) of the Super Hornet will be offered to Finland. The answer was simple, with Bryan Crutchfield explaining that it was up to the customer, and: “As a mainly single-seat air force, I would expect Finland to primarily be interested in F/A-18E.” This lead to the natural follow-up question, why the equally mainly single-seat Royal Danish Air Force was offered only the two-seat F/A-18F, a decision which proved to be something of a decisive issue in the Kampfly-program. “Because they only asked for the two-seater,” Bryan explained. On the question of why, he had no direct answer, but this is yet another strange data point in the already rather murky Danish affair.

For Finland, a small number of F/A-18F would likely be acquired for advanced training, with a secondary fighter/strike tasking. Source: Own picture

More interesting then was that Boeing seemed to assume that Finland would be interested in a number of Growlers as well. In the case of the US Navy, roughly 20% of the Super Hornets bought are of the electronic warfare version, meaning that a potential Finnish mix of Super Hornets could be something along the lines of 40 F/A-18E single-seaters, 12 F/A-18F two-seaters, and 12 EA-18G Growlers, for a combined fleet of 64 fighters. When asked about if the ‘full-spec’ Growler is likely to be released for sale to Finland, Crutchfield was careful not to make any promises, noting that any sale would be a government-to-government deal. However, he went on to say that Finland appears to be a “very trusted” partner in Washington, and pointed to JASSM-deal as an indication that if Finland wants the Growler, there likely wouldn’t be any issues.

The Growler in many ways is an unrivalled platform in the electronic warfare role, being able to not only jam and destroy enemy radars and air-defence systems, but also having a significant capability when it comes to intercepting and jamming enemy communications and signals. The latter has made it a valuable resource in the operations against ISIS, and it is safe to assume that if Finland would acquire a handful of dedicated EW-platforms, it would make us a sought after coalition partner in the kind of low-intensity conflicts we have participated in in Afghanistan and Iraq. The question then is largely about the price of acquiring and operating the Growlers, as well as what kind of a loss having only 40 instead of 52 F/A-18E’s would be in the eyes of the Air Force Command. While the size reduction in ‘true’ fighters is significant, the role of the Growlers as force multipliers might provide a huge enough boost for both the Air Force and, crucially, to the ground forces to warrant this. As said, this is not solely a question of providing SEAD, but also of the Growlers being able to increase the fog of war for the enemy at crucial moments.

“Envelop the enemy in the fog of war, sow confusion while providing time and space for one’s own forces. Jam the adversaries’ radars. Disrupt his communications. Induce indecision; make the enemy question his own equipment and make mistakes.”The mission of the Growler as described by the Growler Industry Team

But even without the Growler, the baseline F/A-18E/F is a highly versatile multirole aircraft. “The most capable combat-proven multi-role aircraft”, as Boeing likes to put it (a statement that will upset the French). In addition to ‘normal’ air-to-air and air-to-ground work, the aircraft is able to handle both the maritime strike (Boeing did feature a scale model of a Harpoon anti-ship missile in their stand) as well as SEAD, two missions discussed at length in the Finnish report at the launch of the HX-project. What makes the SEAD-mission possible is the Integrated Defensive Electronic Countermeasures (IDECM)-package, currently in its Block IV state, coupled with the ‘leakage’ of technology developed for the Growler back into the fighter version of the aircraft.

“Physics matter,” Crutchfield sums up the sensor package, and point towards the large nose of the F/A-18E parked behind us during the interview. The nose hoses the AN/APG-79 AESA radar built by Raytheon, and Crutchfield isn’t shy when talking about the capabilities of the radar, stating that it is ‘generations’ in front of the competition, with rolling upgrades being introduced every two years. It should be remembered that the AN/APG-79 did experience some rather significant teething troubles when first introduced into service, though things seems to have gotten better since. One of the key features of the AESA is that it allows the pilot of the F/A-18F to stay fully focused on the air-to-air picture, while the weapon system operator (WSO) in the aft seat works on the air-to-ground view, with both having access to the radar modes they want.

Like the ‘legacy’ Hornet before it, the Super Hornet is qualified for a large number of weapons, including the most recent versions of the venerable AIM-9 Sidewinder, the AGM-88 HARM, and the AIM-120 AMRAAM (these being the AIM-9X, AGM-88E AARGM, and the AIM-120D respectively). On the horizon the SDB-II and the LRASM looms, while more exotic munitions include the Quickstrike-series of air-dropped mines. Which of these would be of interest to the Finnish Air Force is uncertain, but a continued reliance on ever more advanced versions of the AIM-9/-120 combination would be a natural choice for the immediate future. The big deficit is the lack of the very-long range Meteor ramjet-powered missile, which all other HX-contenders are set to have received prior to HX’s IOC date. The US Navy seems content with traditional rocket-powered air-to-air weapons at the moment, and while Finland naturally could pay for Meteor integration on its own, that would still make be a considerable sum. Going for the Super Hornet could then mean having to get closer to the enemy before firing, as there is a significant difference in the size of the no-escape zones of the throttleable ramjet motor compared to traditional rockets.
